Supercontinuum generation in optical fibers is one of the most dramatic nonlinear effects discovered, allowing short pulses to be converted into multi-octave spanning coherent spectra. However, generating supercontinua that are both coherent and broadband requires pulses that are simultaneously ultrashort with high peak power. This results in a reducing efficiency with increasing pulse repetition rate, that has hindered supercontinua at microwave line spacing, i.e. 10s of GHz. Soliton… 
Mode-locked short pulses from an 8 μm wavelength semiconductor laser
It is demonstrated that careful quantum design of the gain medium and control over the intermode beat synchronization enable transform-limited picosecond pulses from QCL frequency combs, and that both anti-phase and in-phase synchronized states exist in QCLs.
Monolithic piezoelectric control of soliton microcombs
This work demonstrates voltage-controlled soliton initiation, tuning and stabilization with megahertz bandwidth, and monolithically integrates AlN actuators on ultralow-loss Si3N4 photonic circuits, which endows soliton microcombs with integrated, ultralowing-power and fast actuation, expanding the repertoire of technological applications ofmicrocombs.
III-V-on-Silicon-Nitride Mode-Locked Laser with 2 pJ On-Chip Pulse Energy
We demonstrate a III-V-on-silicon-nitride electrically pumped mode-locked laser emitting at λ = 1.6 µm with an on-chip pulse energy of approximately 2 pJ, significantly higher than on III-V-on-Si and
